They begin their life as stem cells, and they mature into three main types of cells— RBCs, WBCs, and platelets. In turn, there are three types of WBC—lymphocytes, monocytes, and granulocytes—and three main types of granulocytes (neutrophils, eosinophils, and basophils). See them in action in "Meet the blood cells".

What is a cell?

(sel) In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and controls the substances that go into and out of the cell.

What are different types of cell?

There are two distinct types of cells: prokaryotic cells and eukaryotic cells. Though the structures of prokaryotic and eukaryotic cells differ (see prokaryote, eukaryote), their molecular compositions and activities are very similar. The chief molecules in cells are nucleic acids, proteins, and polysaccharides.

Why is it called cell?

A cell is the basic unit of life as we know it. It is the smallest unit capable of independent reproduction. Robert Hooke suggested the name 'cell' in 1665, from the Latin cella meaning storeroom or chamber, after using a very early microscope to look at a piece of cork.

What are human cells made of?

Cells are made of proteins, which are a type of molecule, and water, which is another molecule, and other things which are all made of molecules. Molecules are the collections of atoms, that is Water is composed of Oxygen and Hydrogen atoms, Proteins are made of Carbon, Hydrogen, Oxygen, and different components.

What are cells named after?

Hooke detailed his observations of this tiny and previously unseen world in his book, Micrographia. To him, the cork looked as if it was made of tiny pores, which he came to call “cells” because they reminded him of the cells in a monastery.

What is a cell called?

The cell (from the Latin word cellula meaning 'small room') is the basic structural and functional unit of life forms. Every cell consists of a cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.
